I have an LP problem with 20000 variables, 20 constraints and a dense constraint matrix. Any advice on the solver settings (CLP thru OSI) that I should use to speed up the solution process (I want to run this as part of an interactive solution). For example, is it worth switching presolve off, etc?<br><p>
